CS Focus
The site is organized around computer science work rather than media
logs: what I am learning, what I am building, and what I want to explain
clearly later.
Operating Systems
Operating systems, networking, databases, and the layers that make software real.
Linear Algebra
Vectors, matrices, transformations, and the math that keeps algorithms honest.
Natural Language Processing
Language models, retrieval, evaluation, and systems that work with human text.
Computer Vision
Images, representations, perception pipelines, and visual understanding.
Cryptography
Security assumptions, protocols, privacy, and the rigor behind trusted computation.
